Harold Whyman - Experimental Manager} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}13/MH.{M. Huckerby}6.1.38. WRAITH CRANKSHAFT. The Design Office want to fit Packard type balance weights to Wraith crankshaft in preparation for Phoenix. Will you, therefore, let W.Bell have a Wraith crankshaft so that he can carry out the usual deflection tests to determine the correct position and the amount of balance required.
